The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Overview
This desktop C-clamp is built for mounting rather than clamping force. The two threaded holes, 1/4 inch and 3/8 inch, match the standard mounting threads on lights, microphone arms, cameras, and similar accessories, so it acts as an anchor point on a desk or table edge.
At $12.99 it is one of the cheaper options in this batch, and the numbers are healthy: 4.6 stars across 558 reviews with 200 buyers in the last month. That demand clears the floor comfortably and signals owners are getting what they expect.
The listing gives a weight of 0.3 kilograms and no other specs, no jaw capacity, throat depth, or material. That light weight fits its role as a mounting clamp rather than a tool for holding workpieces under heavy load.
